TPU (Thermoplastic Polyurethane) is a versatile 3D printing filament known for its flexibility and strength. It combines the properties of rubber and plastic, offering high elasticity, excellent abrasion resistance, and durability. TPU prints at a temperature range of 210°C to 230°C and is ideal for creating flexible parts like gaskets, seals, and wearable items. Its resilience and ability to withstand stress make TPU a popular choice for functional prototypes and end-use parts that require flexibility and robustness.
